Awadhi is a language spoken by more than 45 million people.[citation needed] The language is ranked 29th out of the most spoken languages in the world and is mainly heard in India, Pakistan (mainly Karachi), Nepal, Fiji, Guyana, Malaysia and Mauritius. Most speakers of the language speak it as a first, not second, language. Awadhi belongs to the Indo-European language family. The writing system used for Awadhi is usually Devanagari or Kaithi, although some people use a mixture of both, and Muslims use the Persian script.

The 2001 census identified Awadhi as a language/dialect having more than one and a half million speakers speaking it as their mother tongue. It was grouped under Hindi.[5] As per the census of 2011, number of Awadhi speakers have increased considerably.

Although today it is only considered a dialect of Hindi, before the standardization of Hindi, it was one of the two most important literary dialect of Hindustani (the other being Braj Bhasha). Important works in Awadhi are the Candayan of Maulana Da’ud, the Padmavat of Malik Mohammad Jaisi (1540 A.D.), the Ramcharitmanas of Tulsidas (1575 A.D.), Indravati by Nur Muhammad (1757 A.D.). [6] Most of the North-Indian Hindu literature, including Chalisas such as Hanuman Chalisha, are written in Awadhi.

Amitabh Bachhan has used Awadhi in his many movies and songs like Holi Khere Raghuvira Awadh Ma from Baghban and Ek Rahe Eer Ek Rahe Beer from Bhootnath. Recently in a serial Yudh (TV series) aired on Sony Entertainment Television (India), he delivered few dialogues in Awadhi which was very well appreciated by the Media. According to Hindustan Times, "We simply loved Amitabh Bachchan speaking Awadhi on TV! Only an actor of his calibre could transform himself from a high-class English speaking businessman to rattle off the dialogues in Awadhi, his mother tongue. He has done it in the past for a few Bollywood and regional films, but not as regularly as one would have liked him to show off grasp over the language. It was great to see him speak in fluent Awadhi in Wednesday's episode."[9]

Awadhi can roughly claim to be the language of the tract lying between Bareilly to Allahabad, north of the Yamuna river and south of Mahabharat range in Nepal, cornered by Etawah in south-east and Khalilabad of Basti Janpad in northeast. This makes Awadhi as the singly the most widely spoken dialect of Hindi.

Note that the above table is mostly based on talking to a male who is older or of the same age. At other times, "tumar" tends to be "tohaar" and "tor" (for a younger person). While talking to someone, people often use the word "falane" or "falana" to refer to someone unnamed or unknown, like, "Falana ke bappa hinya aye rahain" which means, His (which is unnamed or he who can not be named) father has come here.

This is used in occasions when the mother does good things for her son, but the son is evil and does not consider his mother's good doings.
